While the women are only three years apart, Cher, 72, plays the mother of Streep, 69, in the film and says she was “thrilled to death” to do it.

“That doesn’t make any difference,” said Cher in an interview with People.

“I was thrilled to death, and it was so silly. It was great fun, and I love her [Meryl], so it was perfect. It was great, and she was hiding watching me sing, and I was so excited. I didn’t find out until afterwards — I would have been more nervous.”
